What is the difference between deterministic finite automata and non deterministic finite automata?
A deterministic Finite Automata)DFA will have a single possible output for a given input.The answer is deterministic because you can always feel what the output will be.
A (Nondeterministic Finite Automata)NFA will have at least one input which will cause a "choice" to be made during a state transition,unlike a (deterministic Finite Automata)DFA one input can cause multiple outputs for a given (Nondeterministic Finite Automata)NFA.

Difference between deterministic finite automaton and non deterministic finite automaton?
The state machine described in the previous section is a deterministic finite automaton, in which each state is unique. What would make a finite automaton nondeterministic is if each state was not. For the example, if the state machine allowed the input to have any letter as the second letter for the word "person" to transition to the next, then the next state would not be unique, making it a nondeterministic finite automaton.
Describe how lexical analyzer generators are used to translate regular expressions into deterministic finite automata?
Lexical analyzer generators translate regular expressions (the lexical analyzer definition) into finite automata (the lexical analyzer). For example, a lexical analyzer definition may specify a number of regular expressions describing different lexical forms (integer, string, identifier, comment, etc.). The lexical analyzer generator would then translate that definition into a program module that can use the deterministic finite automata to analyze text and split it into lexemes (tokens).
What are the limitations of finite automata?
The defining characteristic of FA is that they have only a finite number of states. Hence, a finite automata can only "count" (that is, maintain a counter, where different states correspond to different values of the counter) a finite number of input scenarios.There is no finite automaton that recognizes these strings:The set of binary strings consisting of an equal number of 1's and 0'sThe set of strings over '(' and ')' that have "balanced" parenthesesThe 'pumping lemma' can be used to prove that no such FA exists for these examples.
Difference between active and passive elements?
Active components can deliver a finite amount of power for some finite amount of time period where passive components can not deliver finite amount of power for some finite amount of time.
Can DFA simulate NFA?
Yes, a Deterministic Finite Automaton (DFA) can simulate a Non-deterministic Finite Automaton (NFA). This can be achieved by constructing an equivalent DFA for a given NFA using the subset construction method. In this method, each state of the DFA represents a set of states of the NFA, and transitions are defined based on the transitions of the NFA. By following this approach, a DFA can effectively simulate the behavior of an NFA.
What is full form of DFA and NFA?
DFA - deterministic finite automata NFA - non-deterministic finite automata
Are all deterministic finite automata (DFAs) also non-deterministic finite automata (NFAs)?
No, not all deterministic finite automata (DFAs) are also non-deterministic finite automata (NFAs). DFAs have a single unique transition for each input symbol, while NFAs can have multiple transitions for the same input symbol.
Difference between deterministic finite automata and non deterministic finite automata?
A deterministic finite automaton will have a single possible output for a given input. The answer is deterministic because you can always tell what the output will be. A nondeterministic finite automaton will have at least one input which will cause a "choice" to be made during a state transition. Unlike a DFA, one input can cause multiple outputs for a given NFA.
Is it possible to show that all deterministic finite automata (DFA) are decidable?
Yes, it is possible to show that all deterministic finite automata (DFA) are decidable.
What does dfa stand for?
Deterministic finite state automata
What is dfa and nfa?
DFA - Deterministic Finite Automata NFA - Non-Deterministic Finite Automata Both DFAs and NFAs are abstract machines which can be used to describe languages.
Define the languages accepted by NFA and DFA?
In general, finite state machines can model regular grammars. Deterministic finite automata can represent deterministic context-free grammars. Non-deterministic finite automata can represent context-free grammars.
Is it possible to demonstrate that all deterministic finite automata (DFA) are in the complexity class P?
Yes, it is possible to demonstrate that all deterministic finite automata (DFA) are in the complexity class P.
What is difference between finite state automaton and transition graph?
finite automata
Difference between DFA and NFA?
Hi, 1. DFA cannot use empty string transition and NFS can use empty string transition. 2. It use one machine but it use multiple machine. 3. DFA is one state transition but NFA react according to some symbol.
Difference between NFA and NDFA in automata?
when power feature non-determinism is added to finite automata then it is known as NDFA when an input is read the automata each step may chose to go to any of the several possible(legal) "next states " . Since the choice is not determined by anything , therefore , it is valled non deterministic.
How can the union of two deterministic finite automata (DFA) be achieved?
The union of two deterministic finite automata (DFA) can be achieved by creating a new DFA that combines the states and transitions of the original DFAs. This new DFA will accept a string if either of the original DFAs would accept that string.
